'The amazing cognitive, emotional, and moral capacities of ... animals'

From Moral in Tooth and Claw by Jessica Pierce and Marc Bekoff :

Animals are "in." This might well be called the decade of the animal. Research on animal behavior has never been more vibrant and more revealing of the amazing cognitive, emotional, and moral capacities of a broad range of animals. That is particularly true of research into social behavior—how groups of animals form, how and why individuals live harmoniously together, and the underlying emotional bases for social living. It's becoming clear that animals have both emotional and moral intelligences.

Philosophical and scientific convention, of course, has pulled toward a more conservative account of morality: Morality is a capacity unique to human beings. But the more we study the behavior of animals, the more we find that different groups of animals have their own moral codes. That raises both scientific and philosophic questions.

Researchers like Frans de Waal (The Age of Empathy: Nature's Lessons for a Kinder Society), Elliott Sober, David Sloan Wilson (Unto Others: The Evolution and Psychology of Unselfish Behavior), and Kenneth M. Weiss and Anne V. Buchanan (The Mermaid's Tale: Four Billion Years of Cooperation in the Making of Living Things) have demonstrated that animals have social lives rich beyond our imagining, and that cooperation and caring have shaped the course of evolution every bit as much as competition and ruthlessness have. Individuals form intricate networks and have a large repertoire of behavior patterns that help them get along with one another and maintain close and generally peaceful relationships. Indeed, Robert W. Sussman, an anthropologist at Washington University in St. Louis, and his colleagues Paul A. Garber and Jim Cheverud reported in 2005 in The American Journal of Physical Anthropology that for many nonhuman primates, more than 90 percent of their social interactions are affiliative rather than competitive or divisive. Moreover, social animals live in groups structured by rules of engagement—there are "right" and "wrong" ways of behaving, depending on the situation.
